| With the constant progress of science and technology,smart home market is rapidly growing,its application areas and applicable industry also increasingly widespread,and in smart home system of network and information security,also began to exposed in front of us,science and technology is a double-edged sword,if not a sufficient security protection,convenient intelligent terminal of our lives,It can also be a breach of our personal information.At present the rapid development of Internet and Internet technology,on the market with the variety and number of rich and different function of intelligent terminal,and due to different manufacturers,technology,function of different factors such as limit,cause there is no a unified standard or platform can be compatible with an allencompassing gesture all the products,Also exposed the unable to solve the problem of safety protection in terminal level,in this paper,based on this background and requirements,designs and realizes a filter in the network layer,the application layer to verify the safety of the gateway system,the existing of ubuntu system,according to the custom demand to optimization of system,the function of the realization of safety protection.This paper studies the smart home security gateway system,and the main work is as follows:First,according to the Radius authentication process algorithm,Radius authentication algorithm is applied on the smart home security gateway to realize identity authentication and encryption based on RSA message digest algorithm MD5.The second is the overall design and implementation of the security gateway system.Through the reference and research on the characteristics of each module of the existing security gateway system,the structure design and function realization of the system are completed.The gateway designed in this paper uses wireless AP and DHCP functions to access terminals.At the same time,different accounts are assigned to different terminals to avoid horizontal movement caused by single account being guessed.By encrypting the text such as password with MD5 based on RSA message digest algorithm,the security of code can be improved,and the accuracy of data processing can be improved in the security gateway system.Use Python language to write scripts to complete the assembly and sending of data packets;In terms of authentication information,Radius is used for authentication.The various functions of the smart home security gateway system are tested to verify that the security gateway system has a certain reliability and stability.This design is based on the use of existing technology optimization ideas to solve the current problems,the existing technology according to the problem to solve the secondary development,in order to better adapt to the current design,for further development suitable for practical engineering applications of the security gateway system provides a solution.However,the design of this paper also has some defects,network information security problems are changing with each passing day can not solve all problems once and for all,the use of technology there is still room for innovation,can be further updated and optimized.Figure[29]Table[0]Reference[49]... |
